Previous research highlighted that pupils actively involved in bullying and victimization are prone to develop diverse psychological problems. The overall aim of our study was to investigate effects of different forms of bullying and victimization on coping with interpersonal stressors and psychological adjustment among children and adolescents. Moreover, the additional contribution of coping in the prediction of effects of direct and relational bullying on psychological adjustment was examined. Four hundred and nine 6th to 9th graders (aged 10-16 years) completed self-report measures, which assessed experiences with bullying and victimization, coping strategies and psychological problems. All forms of victimization were characterized by an increased maladaptive coping as well as heightened emotional and behavioral problems with the most unfavorable pattern among pupils confronted with direct as well as relational victimization. Direct aggressors only and pupils bullying others directionally and relationally showed enhanced externalizing problems. Regression analyses indicated that the adverse effects of direct and, to a lesser degree, relational bullying and victimization on psychological adjustment were primarily enhanced by maladaptive coping among girls and boys. By applying preventive interventions, which are tailored to special needs of the groups actively involved in bullying and victimization, the risk for the development of psychological problems may be effectively diminished.
